NATHAN H. DAVIS, OF PHILADELPHIA, PENNSYLVANIA.

BRAKE-HEAD.'

SPECIFICATION forming part of Letters Patent No. 683,730, dated October 1,1901.

Application filed May 13, 1901.

To all whom it may concern:

Be it known that I, NATHAN H. DAVIS, a citizen of the United States of America, residing in the city and county of Philadelphia, in the State of Pennsylvania,l1ave invented a certain new and useful Improvement in Brake-Heads, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to the construction of brake-heads, and has for its object to provide a cast-metal brake-head of great strength for the amount of metal required in its construction.

The nature of my improvements will be best understood as described in connection. with the drawings, in which my improved brake-head is illustrated, and in Which- Figure 1 is a side elevation of the brakehead; Fig. 2, a front-view thereof; Fig. 3, a side elevation taken on the section-line 3 3 of Fig. 2; Fig. 4, a cross-section on the line 4 4: of Fig. 1; Fig. 5, a cross-section on the line 5 5 of Fig. 1, and. Fig. 6 a cross-section on the line 6 6 of Fig. 1.

A indicates the socket portion of the brake- .head, which may be of whatever shape is required to fit upon the ends of the brake-beam employed. As shown, the socket portion is adapted to receive a generally cruciform brake-beam end, being formed with a transverse perforation having an arm A, from the 'base of which extend the transverse arms A and A, while opposite to it lies the arm A of generally circular section connected with the base of the arms A and A by a neck A This particular form of socket is designed for use with my brake-beam described and claimed in application for Letters Patent filed May 13, 1901, Serial No. 59,943.

B B are the outwardly-extending arms of the brake-head, which are made of U shape in cross-section, as indicated at B, the head of the U terminating before its legs, as indL cated at B B and the legs or sides of the U being continued, as indicated at B and provided with terminal platforms 13, upon which the ends of the brake-shoe are designed to rest. From the inner side walls of the U- shaped arms B extend the arms 0, which sup- Serial No. 59,944. (No model.)

port the stirrups C 0, against which the wedge used with this style of brake-head rests. My brake-head as a whole is, as will be seen, hollow, and to strengthen it I provide between the socket and the stirrup O a transverse connection D, which is preferably U- shaped, as indicated at D and the ends D of which should terminate, as shown, at some distance back of the stirrup C, so as to give a clear passage for the wedge. I

At a a (shown in Figs. 5 and 6) I have indicated rivet-holes, which may sometimes be conveniently provided as a means of securing the socket to the ends of the brake-beam.

While I prefer to make the arms 13 B of hollow U -shaped section, it is within my conception and invention to form them, at least in part, of tubular section between the points indicated. at I) Z), Fig. 3, where the arms of the U may be connected, as indicated in dotted lines at b, Fig. 4:, the connecting portion being of course omitted where it would interfere with the passage of the wedge which holds the shoe in place.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hollow cast-metal brake-head having hollow arms B B provided with terminal platforms for the brake-shoe, wedge-holding stirrups O C supported on extensions 0 C from the inner'sides of said hollow arms, and a transverse U-shaped connection D uniting the walls of the head lying back of said stirrups.

2. A hollow cast-metal brake-head having a socket A adapted to receive the end of a brake-beam, hollow arms B 13 extending from said socket portion and provided with terminal platforms for the brake-shoe, wedge-holding stirrups C 0 supported on extensions from the inner sides of the arms B B and a transverse U-shaped connection D uniting the sides of the head.

3. A hollow cast-metal brake-head having arms B B of U-shaped section provided with terminal plat forms for the brake-shoe, wedgeholding stirrups O 0' supported on extensions O C from the inner sides of said U- shaped arms, and a transverse U shaped conneetion D uniting the walls of the head lying on extensions from the inner sides of the back of said stirrups. arms B B and a, transverse U-shaped conneo- 1o 4.
